Radio node and radio communication control method

Abstract

A radio node includes a control section that configures a parameter related to a transmission timing for a synchronization signal block based on units of second time period, the synchronization signal block being transmitted in accordance with a transmission periodicity in the second time period different in length from a first time period, and a transmission section that transmits the parameter configured.
